<p:未找到graphicImage src 404

Question

我正在尝试阅读一些插入到我的项目中的图像，但我做不到。我创建了一个maven Dynamic Web Module 3.0项目，并在web内容中插入了resources / images文件夹。我在构建路径中添加了这个文件夹，因为我认为它是不可访问的，但它不起作用。

我尝试过不同的编码模式：

<p:graphicImage value="resources/images/chardonnay.png"/>
<p:graphicImage value="#{resource['images/muller.png']} />
<p:graphicImage value="#{resources['images:muller.png']} />
<p:graphicImage library="images" name="riesiling.png"/>

这是我的项目的结构

解决了。

在web.xml中

<context-param>
    <param-name>javax.faces.WEBAPP_RESOURCES_DIRECTORY</param-name>
    <param-value>/WEB-INF/resources</param-value>
</context-param>
